All four of the well-known out candidates competing to succeed termed out Supervisor Bevan Dufty in 2010 have agreed to attend the event. Dufty, who is running for mayor in 2011, will also be on hand at the public’s first chance to meet and greet the wannabe supes contenders. The town hall will run from 7 to 9 p.m. Tuesday, October 27.

The idea to split Alice’s nod between the two former co-chairs of the club is roiling the more moderate LGBT political group and has incensed the campaign of Laura Spanjian, another past Alice co-chair.

Along with shutting Spanjian out of the competition for Alice’s endorsement, the proposal would also block former Alice board member Rafael Mandelman from the endorsement process altogether. Wiener’s and Prozan’s backers say they have the votes needed to push through the dual endorsement, but Spanjian’s supporters have been hitting the phone lines to try to stop it in its tracks.

The Alice board meets behind closed doors, so it will be interesting to see if the internal club dispute spills out into the open Tuesday night.

That same evening the more progressive Harvey Milk LGBT Democratic Club is set to vote on whether to give its endorsement in the D8 race to Mandelman, its current president. Considering none of the other candidates plan to be at the Milk Club meeting, which starts at the same time as the town hall, it is a safe bet that Mandelman has the endorsement locked up.

Magnet is located at 4122 18th Street, while the Milk Club meeting takes place at the Women’s Building at 3543 18th Street.
